Short answer: the QSC K12.2. It ranks #1 of 83 12-inch pa speakers by sound quality, rated 4.7/5, at $899.99; the Vue Audiotechnik A-12 ranks #45, rated 3.6/5, and costs $1,945, so there is little reason to consider the other one.
The QSC K12.2 is the more accurate, deeper-bass choice. A reliable 12 inch PA speaker with excellent sound and flexible built in processing, a safe choice for most events. Its measured preference score, a predictor of how neutral it sounds, is 5.46 against 2.54 for the Vue Audiotechnik A-12. Its bass reaches about 48Hz before falling 3dB, against 80Hz for the Vue Audiotechnik A-12. It keeps a wired aux input, which the Vue Audiotechnik A-12 lacks. The catch: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
The case for the Vue Audiotechnik A-12: A passive 12 inch PA speaker in a braced birch cabinet, with a rotatable horn and a switch for passive or bi-amp setups. Watch for: Spinorama rates the data quality as low, and a 0.635 listening-window deviation means tonal balance is less even than the leaders in this ranking.
Buy the QSC K12.2. It is rated higher for sound quality than the Vue Audiotechnik A-12 and costs less, which makes it the one to get unless you need something the other one does better.
